iron remover Treatment has manganese dioxide as a catalytic moiety promotes iron oxidation. Basically, iron and oxygen are attracted to manganese dioxide, where INDION-ISR enhances the oxidation of dissolved iron and converts the soluble iron (Fe ++) into insoluble ferric (Fe+++); this can be filtered through the media that acts as catalyst in the process and does not get consumed. In the reaction, manganese dioxide is reduced to manganese oxide and ferric hydroxide is precipitated. During the backwash, the surface of this material is scoured, converting it to MnO2 , which is further used to oxidise the iron. Simple backwash regenerates the manganese dioxide
